License
The theme’s code is yours to use under the terms of your purchase. The fonts, photography and video are third-party: check that each one covers the way you intend to use it, and replace anything that does not. LICENSE.md in the theme root has the full terms.
Font
Barlow Condensed and Poppins come with the theme, in static/fonts/, and are served from your own domain. Both are released under the SIL Open Font License 1.1, which allows their use on any site, commercial ones included.
Images and Video
The photographs and the pricing film are stock placeholders from Freepik that came with the original design, licensed to whoever made it. Replace them with your own or with files you have licensed yourself before you launch, and do not pass them on in anything you share or sell. Freepik's terms depend on the plan a file was obtained under, and some plans require attribution.
